Release Black Ops 2 FastFile decrypter
#1
So this is the release of my BO2 FF (FastFile) decrypter for PC version (not sure what encryption does xbox360 version use)

Not much to say, it just decrypts black ops 2 fast files. Source included.

Credits:
@kokole for making decrypter
@master131 for giving the salsa20 key Heart


.rar   bo2_ff_decrypter_clr.rar (Size: 182.28 KB / Downloads: 1,133)

In it's current state, there's not much to do with this considering I can't get the files that are inside.
Nevertheless great job, to the both of you!

The Xbox 360 version also uses salsa20.
If you want to have a go at a console FF then here is the key.
Code:
ffKey[0x20] = { 0x0E, 0x50, 0xF4, 0x9F, 0x41, 0x23, 0x17, 0x09, 0x60, 0x38, 0x66, 0x56, 0x22, 0xDD, 0x09, 0x13, 0x32, 0xA2, 0x09, 0xBA, 0x0A, 0x05, 0xA0, 0x0E, 0x13, 0x77, 0xCE, 0xDB, 0x0A, 0x3C, 0xB1, 0xD3 };

If you need, I will upload an FF for you later. Just name the one you want.

Bytes look ok with that key, but I can't seem to figure out what compression they use. Take a look at this 2 blocks i've decrypted from patch_mp.ff

I wasn't too sure. Would the method be in the executable? I could decompile that for you.
